Going WeatherFlow for Smart Devices

Weatherflow Windmeter


Feb 22, 2018

For a gloomy February we look not only at how an app that works within your phone can be of benefit to mariners but take a look at an interesting ‘pocket gadget’ that connects externally to your iOS or Android mobile device that could be mighty useful, particularly for you sailors out there. Although this gadget isn’t going to be replacing your onboard equipment anytime soon, sometimes it is just fun to look at new gadgets that are still quite advantageous to boaters. Carry it with you ashore to stay on top of conditions.

Weatherflow, a company with over two decades of experience developing observational, modeling and forecasting technology, has been rapidly expanding on its portable wind and weather meters. Canadians have become fairly reliant on various weather and navigation apps to provide us with current and forecasts, but this tech may not always be available if service is lost. And of course, you can always revert to your standard onboard anemometer, but for those who appreciate gadgets and new tech, Weatherflow’s wind and weather meters offer a simple, easy to use and portable option.

It begins with their portable windmeter that is essentially a pocket-sized anemometer that plugged into your mobile device that read wind speed and direction and recorded on your phone through their app. Since the success of the plug-in wind meter, Weatherflow has taken their anemometer to new heights.

Weatherflow WeathermeterWeatherflow now offers a complete WEATHERmeter that can measure wind (avg, gust, apparent, true), temperature, humidity, heat index, wind chill and pressure readings. And it no longer requires a direct plug in to operate but connects wirelessly to your smartphone up to 100’ feet away. Compatible devices include iPhone 4S or newer, iPad Gen 3 or newer operating on iOS 6.0 or newer and Bluetooth Smart Ready Android Phone and Tablets with operating system 4.3 or newer.

The data gathered by the WEATHERmeter can be viewed through the free Wind & Weather Meter app but is also compatible with other popular weather apps like SailFlow, FishWeather and Wind Alert. Data can also be directly shared instantly through email, SMS, Twitter, Instagram and other comparable platforms.

The device has received extremely positive reviews from both mariners and beyond (marksmen, golfers…). The unique ability to take your weather station with you lets you use it for multiple applications and provides a fun toy while out on the water and when you head inland.

While Canadians may have been slower to warm to pontoon boats than our southern neighbours, that’s definitely changed as we see more of them gracing our waters every year. The latest data shows pontoon boats now represent around 30% of all new boats sold in Canada and it’s easy to understand why – with their interior space and tremendous versatility, pontoons are near-perfect family runabouts.

Cruising Georgian Bay’s 30,000 Islands: Canada’s Freshwater Paradise for Boaters

The Plan

It’s a beautiful morning as we perform our pre-departure checklist, fire up the engines and prepare to release our lines. And if the long-range forecast of very low winds coupled with plenty of sunshine holds, that’s exactly what we need for the areas we plan to explore on this trip! 

We are departing Midland for a week of visiting some of the islands and anchorages within Georgian Bay’s “30,000 Islands” – specifically those along the western edge. These are the less protected islands which face toward wide-open Georgian Bay, where boaters often have to depart the small craft route and work a little harder at setting the hook but are then rewarded with magnificent western views, stunning sunsets, and so much to explore!
